I went through this with my '93 some years ago and it turned out to be fuel drain back due to a faulty check valve in the tank. Check this by pressing the valve on the fuel rail after the Jeep has been sitting awhile and the engine is cold. A strong squirt means that your problem is probably something else.
Solved by adding an inexpensive external check valve off eBay (~$16). Installs easily back by the fuel filter which is probably due for replacement in any event.
Mine now holds full fuel pressure indefinitely and starts first time every time.
